The knuckle boom crane is a convenient and efficient product, which can be moved to the designated position conveniently and quickly during the working process, so as to reduce the working time and improve the working efficiency. 聽 Folding boom cranes are widely used for lifting and handling machinery in ports, workshops, construction sites and other places. 聽 The folding boom crane is simple and fast to install and more flexible in the process of use. It is designed in sections, convenient to install and transport, and can be customized. 聽 The folding boom crane is flexible and versatile, especially suitable for fragile items. It optimizes the assembly process of those items that need to be transferred quickly with high precision; The folding jib crane products are mostly used for auxiliary work, and are mostly used in various industries including engineering machinery, electronic manufacturing, airport, metal processing, automobile parts, etc. The intelligent folding jib crane saves working time to the greatest extent and reduces the overall cost. How does a knuckle boom crane work? The main working power of the knuckle boom crane聽is hydraulic drive. The hydraulic system consists of hydraulic oil tank, oil pump, valve group, hydraulic oil cylinder, hydraulic motor and hydraulic pipeline.聽The oil pump gets its power from the car engine through the power take-off, Using hydraulic oil as the medium,聽the flow direction of hydraulic oil is controlled by the valve group to control the telescopic and luffing of the boom and the rotation of the crane. 聽 The biggest working feature of the knuckle-boom crane is the telescoping with load. 聽When working, the boom is supported, and the goods are transported up and down by the wire rope. The biggest feature is that the boom is long and hoisting high. The folding arm crane has two sets of luffing cylinders. One set of luffing cylinders has the same function as the luffing cylinders of the truck crane, while the other set of luffing cylinders is used to lift cargo. Because the telescopic boom is also driven by the oil cylinder, the driving force is large, the telescopic boom can be pushed and retracted even when the hoisting load is heavy. Therefore, the advantages of the folding arm hanging in the narrow and low space are obvious!Knuckle Boom Cranes suppliers website:http://www.hbqz-crane.com/knuckle-boom-cranes/
